Quickly and easily get an estimate for your RC car's top speed with RC Speed Calculator Pro! Just tell us which car you have, enter some info about your gearing, motor and batteries, and we'll do the rest. 

Record your estimates to compare different car setups, and if you have a speed gun, you can record your actual top speed along with the estimate.  

Info you'll need: 
- Pinion gear teeth
- Battery cells (or voltage)
- Motor Kv rating
- Tire diameter (we can fill this in based on your car type)

Info we probably have already based on your car:
- Spur gear teeth
- Transmission ratio

Please note, our top speed estimates are just that - estimates! We use a formula that works in theory (in perfect, not real-world conditions), but every car and all driving conditions are different, so expect some variation from real measured speeds.

## Key features

- Estimate RC car top speed
- Input gearing, motor, and battery info
- Record speed estimates
- Log actual top speeds
- Compare different car setups
- Pre-filled car data

### 5/5 — Love this app!

*2025-02-08*

This app really helps you when dialing in your setup and it’s pretty accurate.

### 4/5 — Gear Ratio for the Arrma Felony

*2024-11-26*

I like the setup and it is pretty spot on. It helps to gauge where you speed and calculations are at to predict your results. Only not 5stars is because it doesn’t have a voltage cell option to put in. For example 3S fully charged is 12.6 it automatically factors in the voltage for 11.1 at 3.7v per cell.
